Poor mechanic or correctable error

[ronny mulkey]

i'm a little confused on the language used in casebook ruling 2.10.1.f regarding erroneously counting of a goal. Does it mean that the error occurred because the official did not signal the 3 or because the official did not see it clearly a 3?

A shot is clearly behind the 3 point arc but the official did not signal. The coach of the shooting team is able to question the call within the proper timeframe. During the discussion, the opposing coach and scorekeeper point out that there was no signal made. But, the official definitely knows that it was a 3 but he just didn't signal. In this case, it does not matter because the "mistake" was pointed out in time.

My question is what if the same play happened but it was more than 2 dead balls later? The official definitely knows that it was a 3 but for some reason or other he did not signal. Would you just "fix" this because it was poor mechanic or has this got to be a correctable error play? Is this the intent of this rule?
